The black toad (Bufo exsul), also known as the Inyo toad or Deep Springs black toad, is a true toad that lives only in scattered oases in the Deep Springs Valley of Inyo County, California. In fact, its scientific name, Bufo exsul means &#34;exiled toad,&#34; which refers to its species&#39; isolation in a tiny spot in the high desert wilderness of the Californian Great Basin.
